Abstract
A modular semiconductor device includes a pair of generally parallel electronic circuit boards and a plurality of IC packages mounted between the electronic circuit boards. Two or more modular semiconductor devices may be stacked on each other so that memory capacity can be readily enlarged and the function level can be readily improved. A heating, radiating fin of planar or honeycomb structure may be provided in near contact with an IC package.
